[SOLVED] Xen On CentOS 6.2 (x86_64)

I was trying to install XEN on a CentOS 6.2 (x86_64) and following the guide at http://www.howtoforge.com/virtualization-with-xen-on-centos-6.2-x86_64-paravirtualization-and-hardware-virtualization but I ran out of luck.
Please bear with me and let me explain.
I have a web hosted server in Germany and I am nowhere near it.
The server I can reinstall Centos 6.2 minimal install as many times as i want (thank GOD).
Ok now on to business.
After the CentOS 6.2 minimal install I run this commands. Since I want to have the GUI remotely I start by installing the Desktop. and then moving to the guide.

Now if I understand how this works I will have to create 2 different bridges more lets say br1 and br2 with lets say
br1 with IP 1 been the bridge of IP 2 on the VM01
and
br2 with IP3 been the bridge of IP4 on the VM02
That been said i can have only 2 VM's with public IP's

Am I right?
Please advice if I am wrong or if there is another way to do this.
Thanks to all
Ed

PS I forgot one thing .. please be aware that I only have one Physical NIC so i might need to create dummy0-1 for the new bridges. Is that possible? Cause i am trying and i succed on creating them from command line but when i restart centos 6.2 dummy0 goes away. Only eth0 remains.
Thanks again.

Not trying to be falko or anything LOL but here are my 2 cents of contribution just in case anyone needs them.

1) Asked my ISP in Germany to give me the ip's on the same sub-net but they were not able to give me the same as the server since the one where the server is, is already full.
SoA. Server IP xxx.xxx.020.170B. VM's servers new sub-net (4ip's free) xxx.xxx.033.083 -> xxx.xxx.033.086B.1 As you can see the third octec of the IP is totally different.C We need to create a dummy NIC to hold the bridge

The new IP addresses were each routed via my existing public address - and in this scenario I couldn't use NAT, since these are public addresses.

Instead I needed to use a bridge.

In my case Centos6.2 was installed on the server by my ISP and it was a minimal install. So I needed to install the desktop environment to make it easier to work with the GUI for my administration team.

From here on guys you are on your own with falkos guide and the net too.

** NOTE Once you guys have installed the first VM you put the next ip in my case xxx.xxx.033.084 as the first VM ip and the netmask 255.255.255.248 in my case but be careful here .. on the VM's GATEWAY you should put the bridge IP which in my case was xxx.xxx.033.083.
Leaving me with my first VM 's eth0 config with this lines on it.
IPADDR= xxx.xxx.033.084
NETMASK=255.255.255.248
GATEWAY= xxx.xxx.033.83

Well in your question yes we are practically wasting one Ip doing nothing.
Let me try to solve this riddle another way that i am thinking.
Sorry about the delay on answering. Had some personal issues.
I will try some things for monday will let you know then.
Thanks

Hi Upsurge I thought you wanted to utilize the gateway Ip in a VM not run a service on that ip in which I think I have succeded too.
Just give me a couple more days to do some more testing and i will let you know.
Thanks

Sorry for being a bother. But the system is currently in production now, and I dont want to mess it up for testing. Could you share what was your idea, maybe I can try locally and then apply on the root server.

I was out for a while I had a car accident and got complicated with pneumonia.
Lucky I am recovered now.
Hi my friend.
Do you still need my help ?
Or did you solved it yourself ??
Let me know
Thanks
Ed
